The compounds of the formula I are produced in general by the following methods.

One process for obtaining the compounds of the formula I comprises reacting an arylsulfonylisocyanate or arylsulfonylisothiocyanate of the formula II ##STR7## wherein R¹, R², X and Z have the meanings defined under the formula I, with an aminopyrimidine or aminotriazine of the formula III ##STR8## wherein R³, R⁴, R⁵ and E have the meanings defined under the formula I.

A further process for obtaining the compounds of the formula I comprises reacting an N-arylsulfonylcarbamate of the formula IV ##STR9## wherein R¹, R², X and Z have the meanings defined under the formula I, and R is phenyl, alkyl or substituted phenyl, with an aminopyrimidine or aminotriazine of the formula III.

Finally, the compounds of the formula I can be produced also by reacting a compound of the formula V ##STR10## wherein R¹, R², R³, R⁴, X and Z have the meanings defined under the formula I, and Hal is chlorine or bromine, with a sulfur salt of the formula VI

    M.sup.⊕⊖ S--R.sup.5                            (VI)

wherein R⁵ has the meaning defined under the formula I, and M.sup.⊕ is an alkali metal cation, alkaline-earth metal cation or ammonium cation.

The resulting ureas of the formula I can if desired be converted, by means of amines, alkali metal hydroxides or alkaline-earth metal hydroxides or quaternary ammonium bases, into addition salts. This is effected for example by reaction with the equimolar amount of a base, and removal of the solvent by evaporation.

The reactions to give compounds of the formula I are performed advantageously in aprotic, inert organic solvents. Such solvents are: hydrocarbons, such as benzene, toluene, xylene or cyclohexane, chlorinated hydrocarbons, such as methylene chloride, chloroform, carbon tetrachloride or chlorobenzene, ethers, such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane, nitriles, such as acetonitrile or propionitrile, amides, such as dimethylformamide, diethylformamide or N-methylpyrrolidine. the reaction temperatures are preferably between -20° and +120° C. The reactions of the coupling processes proceed in general slightly exothermically, and can be performed at room temperature. For the purpose of shortening the reaction time or for initiating the reaction, it is advantageous to apply heat for a short time up to the boiling point of the reaction mixture. The reaction times can advantageously be shortened if desired also by the addition of a few drops of a base as a reaction catalyst. Suitable bases are in particular tertiary amines, such as trimethylamine, triethylamine, quinuclidine, 1,4-diazabicyclo-(2,2,2)-octane, 1,5-diazabicyclo(4,3,0)-non-5-ene or 1,5-diazabicyclo(5,4,0)undec-7-ene. The bases used can however also be inorganic bases, such as hydrides, for example sodium or calcium hydride, hydroxides, such as sodium and potassium hydroxide, carbonates, such as sodium and potassium carbonate, or hydrogen carbonates, such as potassium and sodium bicarbonate.

The final products of the formula I can be isolated by concentration by evaporation and/or by removal of the solvent by evaporation, and purified by recrystallisation or trituration of the solid residue in solvents in which the products are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons.

The intermediates of the formulae II, IV, V and VI are known, or they can be produced by methods analogous to known methods.

The aminopyrimidines and -triazines of the formula III are novel, and were specially developed and produced as intermediates for producing the active substances according to the invention. These intermediates thus form further subject matter of the present invention.

The novel aminopyrimidines and -triazines of the formula III are produced by reacting a compound of the formula VII ##STR11## wherein R³, R⁴ and E have the meanings defined under the formula I, and Hal is chlorine or bromine, with a sulfur salt of the formula VI.

This reaction is performed under reaction conditions which are the same as those for the reaction of the compounds V and VI.

The active substances of the formula I are stable compounds, and the handling of them requires no special precautions.

In smaller applied amounts, the compounds of the formula I are characterised by good selective growth-inhibiting and selective herbicidal properties, which render the compounds excellently suitable for use in crops of useful plants, especially in crops of cereals, cotton, soya-bean, maize and rice. Also destroyed in some cases are weeds which hitherto could be dealt with only by the use of total herbicides.

The mode of action of these active substances is unusual. Many are capable of being translocated, that is to say, they are taken up by the plant and transported to other locations, where they produce the desired effect. It is thus possible for example by surface treatment of perennial weeds to destroy them at the roots. The novel compounds of the formula I are effective in applied amounts which are very small compared with the amounts required to obtain the same effect using other herbicides and plant-growth regulators.

The compounds of the formula I have excellent properties also for regulating plant growth, especially for inhibiting plant growth. Both monocotyledons and dicotyledons are impaired in their growth.

Thus, for example, the leguminosae frequently planted as cover crops in agriculture in tropical regions can be selectively inhibited in their growth by the compounds of the formula I, the result being that soil erosion between the cultivated plants is prevented, without the cover crops being able to compete with the main cultivated crop.

A reduction of the vegetative growth enables in the case of many cultivated plants the crop density to be increased, so that higher yields for the same area of land can be achieved.

An additional factor contributing to the increase in yield with the use of growth inhibitors is that the formation of blossom and fruit benefits to a greater extent from the nutritive substances, because the vegetative growth is restricted.

With larger applied amounts of active substance, all the tested plants are impaired in their development to the extent that they wither.

The invention relates also to herbicidal and plant-growth regulating compositions containing a novel active ingredient of the formula I, and also to processes for the pre- and post-emergence controlling of weeds, and for the reduction in growth of monocotyledonous and dicotyledonous plants, particularly that of grasses, tropical cover crops and side shoots of tobacco plants.

The compounds of the formula I are used either in an unmodified form or preferably in compositions, together with auxiliaries customarily employed in formulation practice, and are thus processes, in a known manner, for example into the form of emulsion concentrates, directly sprayable or dilutable solutions, diluted emulsions, wettable powders, soluble powders, dusts or granulates, and also encapsulations in for example polymeric substances. The application processes, such as spraying, atomising, dusting, scattering or pouring, and likewise the type of composition, are selected to suit the objects to be achieved and the given conditions.

The formulations, that is to say, the compositions or preparations containing the active ingredient of the formula I and optionally a solid or liquid additive, are produced in a known manner, for example by the intimate mixing and/or grinding of the active ingredients with extenders, such as with solvents, solid carriers and optionally surface-active compounds (tensides).

Suitable solvents are: aromatic hydrocarbons, preferably the fractions C₈ to C₁₂, such as xylene mixtures or substituted naphthalenes, phthalic esters, such as dibutyl-or dioctylphthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols, as well as ethers and esters thereof, such as ethanol, ethylene glycol, ethylene glycol monomethyl or -ethyl ethers, ketones, such as cyclohexanone, strongly polar solvents, such as N-methyl-2-pyrrolidone, dimethylsulfoxide or dimethylformamide, as well as optionally epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.

The solid carriers used, for example for dusts and dispersible powders, are as a rule natural mineral fillers, such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties, it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, ground brick, sepiolite or bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. There can also be used a great number of pre-granulated materials of inorganic or organic nature, such as in particular dolomite or ground plant residues.

Suitable surface-active compounds are, depending on the nature of the active substance of the formula I to be formulated, nonionic, cationic and/or anionic tensides having good emulsifying, dispersing and wetting properties. By `tensides` are also meant mixtures of tensides.

Suitable anionic tensides are both so-called water-soluble soaps as well as water-soluble, synthetic, surface-active compounds.

Soaps which are applicable are the alkali metal, alkaline-earth metal or optionally substituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), for example the Na or K salts of oleic or stearic acid, or of natural fatty acid mixtures, which can be obtained for example from coconut oil or tallow oil. Also to be mentioned are the fatty acid-methyl-taurine salts.

So-called synthetic tensides are however more frequently used, particularly fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are as a rule in the form of alkali metal, alkaline-earth metal or optionally substituted ammonium salts, and contain an alkyl group having 8 to 22 C atoms, `alkyl` including also the alkyl moiety of acyl groups, for example the Na or Ca salt of ligninsulfonic acid, of dodecysulfuric acid ester or of a fatty alcohol sulfate mixture produced from natural fatty acids. Included among these are also the salts of sulfuric acid esters and sulfonic acids of fatty alcohol ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and a fatty acid group having 8-22 C atoms. Alkylarylsulfonates are for example the Na, Ca or triethanolamine salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid-formaldehyde condensation product. Also suitable are corresponding phosphates, for example salts of the phosphoric ester of a p-nonylphenol-(4-14)-ethylene oxide adduct, and phospholipides.

Suitable nonionic tensides are in particular polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 3 to 10 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.

Further suitable nonionic tensides are the water-soluble polyethylene oxide adducts, which contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups, with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbon atoms in the alkyl chain. The compounds mentioned usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples of nonionic tensides which may be mentioned are: nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethyleneoxy adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Suitable also are fatty acid esters of polyoxyethylenesorbitan, such as polyoxyethylenesorbitan-trioleate.

In the case of the cationic tensides, they are in particular quaternary ammonium salts which contain as N-substituents at least one alkyl group having 8 to 22 C atoms and, as further substituents, lower, optionally halogenated alkyl, benzyl or lower hydroxyalkyl groups. The salts are preferably in the form of halides, methyl sulfates or ethyl sulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.

The tensides customarily used in formulation practice are described, inter alia, in the following publications:

"Mc Cutcheon's Detergents and Emulsifiers Annual" MC Publishing Corp., Ridgewood, New Jersey, 1981; H. Stache, "Tensid-Taschenbuch" (Tenside Handbook), 2nd Edition, C. Hanser Verlag, Munich, Vienna, 1981; M and J. Ash, "Encyclopedia of Surfactants", Vol. I-III, Chemical Publishing Co., New York, 1980-1981.

The agrochemical preparations contain as a rule 0.1 to 95%, especially 0.1 to 80%, of active ingredient of the formula I, 1 to 99.9% of a solid or liquid additive, and 0 to 25%, particularly 0.1 to 25%, of a tenside.

Whereas commercial products are preferably in the form of concentrated compositions, the preparations employed by the end-user are as a rule diluted. The preparations can for application be diluted down to 0.001% of active ingredient. The applied amounts are usually 0.01 to 10 kg, preferably 0.025 to 5 kg, of active ingredient per hectare.

The compositions can also contain further additives, such as stabilisers, antifoaming agents, viscosity regulators, binders and adhesives, as well as fertilisers or other active ingredients for obtaining special effects.

BIOLOGICAL EXAMPLES Example B1 Herbicidal Action Before Emergence of the Plants

Plastics pots are filled with expanded vermiculite (density: 0.135 g/cm³, water-absorption capacity: 0.565 1/1). After saturation of the non-adsorptive vermiculite with an aqueous active-ingredient emulsion in deionised water, which contains the active ingredient at a concentration of 70.8 ppm, seeds of the following plants are sown on the surface: Nasturtium officinalis, Agrostis tenuis, Stellaria media and Digitaria sanguinalis. The test vessels are subsequently kept in a climatic chamber at 20° C. with an illumination of about 20 k lux and a relative humidity of 70%. During the germination phase of 4 to 5 days, the pots are covered over with light-permeable material in order to raise the local air humidity and watered with deionised water. After the 5th day, 0.5% of a commercial liquid fertiliser (®Greenzit, ex Ciba-Geigy) is added to the water. The test is evaluated 12 after sowing, and the effect on the test plants assessed according to the following scale of ratings:

Example B2: Reduction in Growth of Tropical Leguminous Cover Crops

The test plants (Centrosema plumieri and Centrosema pubescens) are cultivated to the fully grown stage, and then cut back to a height of 60 cm. After 7 days, the active ingredient is sprayed on in the form of an aqueous emulsion. The test plants are maintained at 70% relative humidity and with 6000 lux of artificial light, 14 hours per day, at temperatures of 27° C. by day and 21° C. by night. The test results are assessed 4 weeks after application of the emulsion. The new growth occurring compared with that on the control plants is estimated and weighed, and the phytotoxicity is evaluated. The plants treated with the active ingredients of the formula I show in this test a clear reduction in new growth (less than 20% of the new growth occurring on untreated control plants), without the test plants having suffered damage.

Example B3: Regulation of Growth of Sova-Bean Plants

Soya-beans of the "Hark" variety are sown in plastic containers holding a soil/peat/sand mixture in the ratio of 6:3:1, and are placed into a climatic chamber. By optimum choice of temperature, illumination, fertiliser addition and watering, the plants develop over about 5 weeks into the 5-6 trifoliate stage. At this point, the plants are sprayed until thoroughly dripping wet with the aqueous liquor of an active ingredient of the formula I, the active-ingredient concentration being up to 100 g of active ingredient per hectare. An assessment of the results is made about 5 weeks after application of the active ingredient. The active ingredients of the formula I produce a marked increase in the number and in the weight of the pods on the leading shoots compared with the number and weight of pods on the untreated control plants.

Example B4: Reduction in Growth of Cereals

The cereal varieties Hordeum vulgare (spring barley) and Secale (spring rye) are sown in plastics pots containing sterilised soil in a greenhouse, and watered as required. The young shoots are sprayed, about 21 days after sowing, with the aqueous spray liquor of an active ingredient of the formula I. The amount applied is up to 100 g of active ingredient per hectare, and 21 days after application, the growth of the cereals is assessed. The treated plants show a reduction in the extent of new growth compared with that on the untreated control plants (60-90% of the new growth on the control plants), and also in part an increase in the diameter of the stems of the plants.

Example B5: Reduction of Growth of Grasses

The grasses Lolium perenne, Poa pratensis, Festuca ovina, Dactylis glomerata and Cynodon dactylon are sown, in a greenhouse, in plastics dishes containing a soil/peat/sand mixture (6:3:1), and watered as required. The emerged grasses are cut back weekly to a height of 4 cm, and are sprayed, about 50 days after sowing and one day after the final cutting, with the aqueous spray liquor of an active ingredient of the formula I. The amount of active ingredient corresponds, when converted, to up to 100 g per hectare. The growth of the grasses is assessed 21 days after application.

The compounds of the formula I effect a reduction of new growth of around 10-30%, compared with the new growth of the untreated control grasses.
